Prometheus Materials raises $6M in debt financing

BOULDER — Prometheus Materials Inc., a zero-carbon building materials company, recently raised $6.25 million in debt financing.

According to a Form D filed with the U.S. Securities and Exchange Commission in mid-July, the Boulder company raised the capital from six investors starting on July 9. Prometheus, representatives of which did not respond to requests for comment, was offering a total of $7 million in securities. 

The debt financing comes two years after Prometheus closed on an $8-million Series A financing round led by Sofinnova Partners.

The company said in June 2022 that the Series A capital would be used to begin commercial production of zero-carbon building products such as precast biocomposite and ready-made biocomposite.
